[Clinical classification of chronic odontogenic maxillary sinusitis]

Area of Science:

• Otolaryngology
• Oral and Maxillofacial Surgery
• Infectious Diseases

Background:

• Odontogenic maxillary sinusitis (OMS) is a significant clinical challenge.
• Chronic sinusitis often necessitates complex management strategies.
• Understanding the prevalence and characteristics of OMS subtypes is crucial for effective treatment.

Purpose of the Study:

• To classify the clinical presentation of odontogenic maxillary sinusitis.
• To determine the prevalence of different OMS forms, particularly the latent and open types.
• To outline treatment approaches for chronic OMS.

Main Methods:

• Retrospective analysis of 248 patients diagnosed with odontogenic maxillary sinusitis.
• Clinical classification based on disease course and presentation.
• Evaluation of treatment outcomes, focusing on surgical interventions.

Main Results:

• The majority of odontogenic maxillary sinusitis cases exhibit a chronic course.
• A latent form of OMS was identified in 16.5% of patients.
• An open form of OMS was diagnosed in 51.6% of the study cohort.

Conclusions:

• Chronic odontogenic maxillary sinusitis is the predominant form.
• Accurate classification, including identification of the latent form, is essential.
• Surgical treatment, such as maxillary sinusotomy combined with dental evaluation and management, is a key therapeutic strategy for chronic OMS.
